Tareas domésticas, cuidado de hijos y variables de salud psicosocial en función del género de profesores y no profesores

The main objective of this exploratory study is to discover differences between men and women in performing housework and childcare, analyzing possible relationships with psychosocial health variables. In addition, it seeks to find out if there are also differences based on gender inside and outside the teaching profession. A total of 79 participants who live with their partner (38 teachers and 45 tertiary sector workers) participate in this study. The work design is descriptive-comparative and cross-sectional. The results indicate that women, regardless of their profession, have a higher degree of involvement in childcare. In addition, the group of women also presented higher levels of depression and physical fatigue and worse mood than men. By profession, it is observed that men teachers are less involved than their partners in their children's food, rest, leisure, education and hygiene. All the results are discussed emphasizing the need to implement measures that help improve the women’s well-being and encourage a real co-responsibility between men and women.El objetivo principal del presente estudio exploratorio es descubrir diferencias entre hombres y mujeres en la realización de las tareas domésticas y el cuidado de los hijos, analizando posibles relaciones con variables de salud psicosocial. Además, se persigue averiguar si también existen diferencias en función del género dentro y fuera de la profesión docente. Un total de 79 participantes que viven con su pareja (38 docentes y 45 trabajadores del sector terciario) participan en este estudio. El diseño del trabajo es descriptivo-comparativo y de corte transversal. Los resultados señalan que las mujeres, independientemente de su profesión, presentan mayor grado de implicación en el cuidado de los hijos. Además, el grupo de mujeres también presenta mayores niveles de depresión y de fatiga física y un peor estado de ánimo que los hombres. Por profesiones, se observa que los profesores presentan una menor implicación que sus parejas en la alimentación, el descanso, el ocio, la educación y la higiene de sus hijos. Todos los resultados se discuten enfatizando la necesidad de poner en marcha medidas que ayuden a mejorar el bienestar de las mujeres y favorezcan una corresponsabilidad real entre hombres y mujeres

Diseño de un sistema contable para implementar el eficiente control de las operaciones y/o transacciones financieras que realiza la Asociación Cooperativa Pesquera Centro de Acopio El Cuco de R.L.

Esta investigación tiene por objetivo elaborar un sistema contable para la implementación eficiente del control de las operaciones financieras que realiza la Asociación Cooperativa Pesquera Centro de Acopio El Cuco de R.L. en el municipio de Chirilagua, departamento de San Miguel. La investigación propuesta es de tipo Correlacional, porque estudia la relación entre las variables independientes y dependientes, básicamente lo que se pretende es medir la incidencia que tiene un sistema contable en el control de las operaciones financieras que realiza la Asociación Cooperativa Pesquera Centro de Acopio El Cuco. Se concluye: más de la mitad de las asociaciones cooperativas de la zona 4 (división según CENDEPESCA) no tienen un sistema contable, para que les sirva de ayuda al registrar sus operaciones y de esa manera reflejar la posición financiera en la que se encuentran al final de cada periodo contable, esto trae como resultado que la administración no se proyecte en actividades futuras. En las asociaciones cooperativas pesqueras en estudio se observó que, la mayor parte de los integrantes de dichas asociaciones no poseen ningún grado de alfabetismo, es por ello que no le toman mucha o ninguna importancia al hecho de llevar un control contable de las operaciones financieras que realiza

Impact of Maturation and Vitrification Time of Human GV Oocytes on the Metaphase Plate Configuration

The combination of in vitro maturation (IVM) techniques and oocyte vitrification (OV) could increase the number of useful oocytes in different types of patients. IVM and subsequent OV is the most widely used clinical strategy. Would the results improve if we reverse the order of the techniques? Here, we evaluated survival, in vitro maturation, time to extrude the first polar body (PB), and the metaphase plate configuration of human prophase I (GV) oocytes before or after their vitrification. Specific, 195 GV oocytes from 104 patients subjected to controlled ovarian stimulation cycles were included. We stablished three experimental groups: GV oocytes vitrified and IVM (Group GV-Vit), GV oocytes IVM and vitrified at MII stage (Group MII-Vit), and GV oocytes IVM (Group not-Vit). All of them were in vitro matured for a maximum of 48 h and fixed to study the metaphase plate by confocal microscopy. According to our results, the vitrification of immature oocytes and their subsequent maturation presented similar survival, maturation, and metaphase plate conformation rates, but a significantly higher percentage of normal spindle than the standard strategy. Additionally, the extension of IVM time to 48 h did not seem to negatively affect the oocyte metaphase plate configuration.This research was funded by Department of Biotechnology of the University of Alicante (VIGROB-186)

Sex-dependent calcium hyperactivity due to lysosomal-related dysfunction in astrocytes from APOE4 versus APOE3 gene targeted replacement mice

Background The apolipoprotein E (APOE) gene exists in three isoforms in humans: APOE2, APOE3 and APOE4. APOE4 causes structural and functional alterations in normal brains, and is the strongest genetic risk factor of the sporadic form of Alzheimer’s disease (LOAD). Research on APOE4 has mainly focused on the neuronal damage caused by defective cholesterol transport and exacerbated amyloid-β and Tau pathology. The impact of APOE4 on non-neuronal cell functions has been overlooked. Astrocytes, the main producers of ApoE in the healthy brain, are building blocks of neural circuits, and Ca2+ signaling is the basis of their excitability. Because APOE4 modifies membrane-lipid composition, and lipids regulate Ca2+ channels, we determined whether APOE4 dysregulates Ca2+signaling in astrocytes. Methods Ca2+ signals were recorded in astrocytes in hippocampal slices from APOE3 and APOE4 gene targeted replacement male and female mice using Ca2+ imaging. Mechanistic analyses were performed in immortalized astrocytes. Ca2+ fluxes were examined with pharmacological tools and Ca2+ probes. APOE3 and APOE4 expression was manipulated with GFP-APOE vectors and APOE siRNA. Lipidomics of lysosomal and whole-membranes were also performed. Results We found potentiation of ATP-elicited Ca2+responses in APOE4 versus APOE3 astrocytes in male, but not female, mice. The immortalized astrocytes modeled the male response, and showed that Ca2+ hyperactivity associated with APOE4 is caused by dysregulation of Ca2+ handling in lysosomal-enriched acidic stores, and is reversed by the expression of APOE3, but not of APOE4, pointing to loss of function due to APOE4 malfunction. Moreover, immortalized APOE4 astrocytes are refractory to control of Ca2+ fluxes by extracellular lipids, and present distinct lipid composition in lysosomal and plasma membranes. Conclusions Immortalized APOE4 versus APOE3 astrocytes present: increased Ca2+ excitability due to lysosome dysregulation, altered membrane lipidomes and intracellular cholesterol distribution, and impaired modulation of Ca2+ responses upon changes in extracellular lipids. Ca2+ hyperactivity associated with APOE4 is found in astrocytes from male, but not female, targeted replacement mice. The study suggests that, independently of Aβ and Tau pathologies, altered astrocyte excitability might contribute to neural-circuit hyperactivity depending on APOE allele, sex and lipids, and supports lysosome-targeted therapies to rescue APOE4 phenotypes in LOAD

Development of a laboratory practice for physics introductory courses using a rubric for evaluation by competences

Competence-based education is oriented towards an evaluation model linked to student training, in order to foster the development of abilities to identify, project, solve problems and make decisions. In this context, the rubrics allow obtaining evidence of the acquisition of competences and application of knowledge outside the classroom. In this work, we present a proposal for the development of a Physics laboratory practice with the use of a rubric for the evaluation by competences in the university field. We want to introduce new assessment methods and identify opportunities to develop skills and evaluate learning through indicators of progress
